FASTENER-INSERTING MACHINE.

Specification of Letters Patent.

Patented May 14, 1912.

, To u/ Z Iir/Loml t may concern/r lic it known that I, STERHEN A.DoBYNE, a citizen of the United States, and residing at St. Louis, inthe State of Missouri, have invented certain new and useful Improvementsin FastenerInserting `Machines, of which the following isaspecification.

This invention relates to fastener inserting machines, and moreparticularly to machines adapted to operate upon shoes.

.llachines of the character referred to, have generally associated withthe fastener inserting .niachines, means for feeding the wei-lt willirespect to the fastener inserting mechanism, a work support, and a gagefor gaging the position where the fasteners are to be inserted in thework. The feeding means generally consist of an awl which alsopunt-,tures or pierces the work to form a hole for the reception of thefastener'.

It is sometimes desirable to drive a fastener or fasteners withoutfeeding` the work, for instance when utilizing the machine to lay soleson shoes. or when building up and temporarily securing lifts on heels inrepair In such cases it is also desirable to withdraw the work gage outof operative position.

Une of the objects of this invention therefore is to constriuft amachine in which the Work feeding mechanism can he thrown into andout ofoperation so as to render it effective and inefl'ectiv(` to t'eed thework at the pleasure of the operator.

Another object is to combine with the above mechanism a work gage whichcan be moved into and out of olierative position with respect to thefastener inserting mechanism.

' 'Another object to improve the Work feeding ,mechanisnn' the gage andthe vfastener inserting mechanism itself as ,to details, and furtherobjects will appear from the detaildescription taken in connection withthe accompanying drawings in which:

Figure 1 is a front elevation of a fastener inserting machine showingone embodiment of this invention, Fig. 2 is a side elevation, Fig. 3 isa plan of the machine column and the gage, Fig. 4 is a'section on theline 4 4 Fig. 2, Figs. 5 and G are sections showing the block connectingthe work feeding member and its actuator inoperative and inop` erativepositions respectively, Figs. 7' and 8 are'details of the actuatorlever, Fig. 9 1s a side elevation of a part of the mechanism showinganother embodiment of this invention, and Fig. 10 is a section on theline 10-10 Fig. 9.

The invention is shown as applied to a fastener inserting machine of theloose nailer type es shown and described in m copending applicationSerial No. 593,330; it will be understood however that the invention maybe equally well applied to other types of fastener inserting machines.rIn this connection itwill be understood that the term fastener insertingmachine is not toY be limited to that type in which the fastener is onlyutilized to fasten parts together, but is intended to cover alsoslugging machines, that is, machines in which nails are driven for wearincreasing purposes.

Referring to the accompanying drawings, A' designates the machine heador frame and B the machine column upon which it is mounted. The headsupports a main driving shaft which is provided with cams and pulleys`to operate the different mechanisms in a manner hereinafter described. Adriver bar 16 having an attached driver 17 is mounted to reciprocate inbearings on the machine head. This driver bar is driven down by means ofa spring 18, and raised against the tension of the spring by means of acam 19 on the shaft 15 engaging a cam roll on the driver bar. A raceway20 slides in guides in a loader C, therotary element of which is drivenfrom the main shaft by a belt and pulley as shown in th'e drawings. Thelower end of the raceway has rigidly secured thereto a nail block orthroat 21, which is provided with adriver passage for the driver, andthe nail block and .raceway are pivoted to the lower end of a link 22which is mounted for swinging movement on .a pivot 23 in the machinehead. A spring pressed plunger 24 operates to lmpve the link and theattached nail block and racewa. in one direction, and a' stop 25 on themac inehead engaging a slot in the link limitsthis movement. A lever 26provided at one end with a roll engaged by the cam 19- operates throughthe plunger 24 to positively return the parts to initial position.l Awork support or pre'sserfoot 27 is secured-to the'ma'- chine head, andforms a support against which *the Workcan be held during the operationofthe machine, either by hand or by beingsupported on a horn or otherwork support "28," The fasteners are fed from the raoeway to the throator driver passagebyv means a separator or picker 29 operated hy means of'a lever flfrom the cam 3l on the mainshal't. i

The support or presserfoot 2 is provided with a sint in width work thetip of the nai block andthe awt 32. This awlV is mounted upon an a'wlcarrier 33, which is provided with a. hollow cylindrical shank 34slidir'ig; in a tubular guidewzty I o'n the rn: Jhinc head and ispressed outwardly h v means vot' a spring 36. An arm 37ml the yawlcarrier has a. connection with an actuating -lever 38 which has a. rollengaging a cam groove on the cam 3l. This' mechanism impart-a a piercingmovement to the awl. 'lhe feed 4 ing move-ment is imparted -to the aivlby means of an actuating lever 39 the lower' end of which bears againstthe awl carrienand' the upper end. pf which is provided with a Cain rollengaginga cam surface on.. the cam' 31.

. The awl actuating n-iechanisin operates to'depressy the avvl so as topierce the Work andi then imparts a feeding move-ment thereto. Thisfeeding movement takes place. while the driver is in raised position,anddu'ring this feeding,movement the awl carrier will eng-age a shoulderBton thev nail block land move,the nail block together provided 'withthe raceway to the left.l After'the feeding movement has been completedand when the. yawl is returned or 'retracted by the icam and the 'spring36, the yieldingly and'positively operated plunger 24 will op-f crate tomove'the nailA block and, raceway back over the holemade by the awl soas to position a fastener.' directly above said hole,'which fasteneristhen driven. r[he lever B9 is provided with an adjusting screw 4Q whichis provided with ajlti'iurlcd head 41 andl has a spring thereon., andthis Screw bears against a stationary StopAO on the machine head. B vmeans of this. construction the feeding movement' of the avt/'l can headjusted. The arm 3 7 on the a wl carrier is provided with a pin orshaft 4?, which receives a block 14. This block slides in the Shaft andarranged to be moved into and ont of engagement with a fork 49 on thelever 38. rlhehlocli el is provided with a. knurled head i5 and arounded' Springr pressed pin i6 which engages longitudinal andcircumferential grooves t? and 48 on the shaft. A stop 48@ prevents theblock from being pulled entirely ott the shaft.

The lower vend of the lever 3U is provided with fixed and movable, lags5l and 52, the lng 52 being scoured to a shaft 53 so as to.. movetherewith. and the shaft 53 'being with a knurled head 54 and a Spring55'. The lug 52 is provided with a ypin or lng 56 arranged to engageeither of two recesses 57 formed in the lever 39.' lThe lug 52 is'arranged 'to engage-anadp-xstable screw 5S) in the awl carrier-and bothof the, lugs 5lj and 52 are provided with holes or recesses so that thescrew 59 maybe manipu- 'lated 'oy .a screw' driver for the purpose ofalining' the' awl with respect to,the driver 'for different-feedswithont necessitating the dismantling lof the. lever 39'.

. A workgage (35 is provided as usual with a gear and rat-.k so as toyhe capable 4of adjustment. handle (3G on the gage carrier (37 isirovided with awlfrear Ilich 'engages the rack-on thel gage'. The `fairecarrier is mounted ilaterallir or on one side of the 'column -or post ,lin split bracket (i8 which is provided Wit-h a. screw so as tofrictionally clamp the carrier in position'.v The Vcarrier is providedIwith astop 69 cooperating with a stop [70 on the cohimn', and it will benoted that these lstops 'arev in line' witlilhe gage, face so that whenthe gage is in operative,- position any 'pressure' brought against itwill tendrather to seat than unseat it. The gage carnbe swung intoan'dout-of operative position 'nnderneathlthe fastener inserting mechanism.

`Vt'hen, the' parts are in the positions shown in the drawings'theactuating mechanisms forft-heawl o r work feeding lmemberhave anoperative'connectionV therewith so 'that the awl is effective.. for'feeding the work. The awl can b e'v thrown ont: of: 'operation and itsfeeding actio'n 'interrpted'in two wayslirst, 'by'interrupting its`piercing aetion, and second, byf interropting its feedf 'ing action, 'orthesetwo gmethods may be used in conjunction to arrestl the 4actions oftheawl, altogether.

In accordance witlrthefrst method the piercing action -of the aw] Vislinterrupted by moving lthe block dlfrom 'full iline to dotted line'position Fig. 1. lVhen the block@ is so withdrawn therc is' siiliioientplay or lost motion between the members 3T and so that lthe movement ofthe actuatorv lever will have practically no effect vuponv (he awl"carrier. ln order that. the awl may be withdrawn from the work andplaced in retracted pmition. a spring 5) having, one end secured tothearm 37 and tl1e, otl1er' endl to the machine head "is arrangedto swingJthe awtcarricr and place the awl in retracted or withdrawn position ont.of the work For this purpose the block is eccentric as showmso that theshaft 43 and the awl carrier can have a movement snfiicient to withdrawthe awl completely from the work,y even'though the lever 38 is ati thethe awl will now be raised so that it will not pass through the presserfoot. lt is therefore no-t necessary that the awl carrier.

be completely disconnected from its actuator-.provided the awl will notin its lowest position pass through the presser foot. The pin and grooveconnection between the block 44 and the shaft 43 is provided so that theblock will be retained in correct position when withdrawn and' thus canbe moved into operative and inoperative positions, even while themachine is running. vThe groove 48 is slightly deeper than the groove 47so that the block will be yieldinglylatched in operative position. Thisblock is, of course, long' enough-to permit the necessary feedingmovement of the awl and its carrier when the block is latched inoperative position, y

`In accordance with the second method the feeding action or movement ofthe awl can be interrupted by swinging the lug 52 out of alinement withthe screw 59 and the awl carrier, the lug being held in the second orinoperative position by the engagement of the pin 5,6 with the other ofthe recesses 57. When the lug is in this last named position there willbe `no feeding engagement between the lever 39 and the awl carrier sothat no feeding movement will be imparted to the awl, the awl carrierremaining in retracted position in which it is placed by the spring 36.In this case the fork 49 forms a stop for limiting' the retractedmovement of the. awl. When the lug is thrown out of the path of thescrew 59, -the spring 36 will move the awl carrier until the head of arm37 abuts against and is stopped by the fork 49. The gap' between 51and'52 is sutlicient so that 51 will not engage or operate the awlcarrier. Any other suitable stop vmay of course be provided to limit theretracted movement of the awl and its carrier. In this case the piercingmovement of the awl is not interrupted but the feeding movement is. Thismay, of course, be objectionable in certain classes of work where it isnot desirable to mar-the work.

It will be understood that the separate means for rendering the workfeeding mechanism inoperative or ineffective may be used.

separately or in conjunction, EachY has its advantages anddisadvantages, thus the first method keeps the nail block and raceway inmotion while the second does not. The former is however advantageouswhere the movement of the raceway is utilized to prevent blogging of thenails as in this specific e bodiment.

igs. 9 and 10 show a construction in which the lever 39 has a plainengaging portion instead of beingprovided with a movable lug 52. In thisconstruction the feeding action is interrupted by the shifting block 44as in the construction shown in the other figures, so as to merelyinterrupt the piercing action of the awl, leaving its movement intheline ofv feed unimpalred. The end of the lever 39 is also provided witha hole or recess 58a for a tool. Similarly the connection between lever38 and the awl carrier may be ya simple connection as in my priorapplication referred to. In this case the feeding operation can beinterrupted by shifting the lug 52so as to interrupt the feedingmovement and action of the awl leaving its piercing action unimpaired.

It is desirable, in some classes of work when the awl isthrownout ofoperation, 'that the gage be also thrown out of the way for instance`when the machine is used for laying soles or for temporarily securingheel lifts in position in repair work. In the sole laying operation, thesole is laid on the shoe or last and a number of fasteners driven alongthe center of the sole or in the channels and heel seat. This, ofcourse, requires a machine which has no gage, and an awl feed is alsonot desirable in this case since it will tend to shift the loosely laidsole out of position. The same'is true of heel repair work. Inaccordance with this invention the machine can be rapidly converted intoa sole laying 'or lift attaching machine, and can also be converted backinto a sole attaching or a slugging machine at the pleasure of theoperator.

It will thus be' seen thatthis invention provides means whereby the workfeeding mechanism can be rendered effective and ineffective at thepleasure. of the operator. This is accomplished by making and breakingthe connection between the work feeding memberand itsactuatingmechanism, or

by raising the member out of engagement with the work and retaining itout of en-y gagement While the fastener inserting mechanism remainsuninterrupted to insert fasteners.- The awl or Work feeding member, canalso be adjusted to vary its feedingT stroke and its position withrespect to the fastener inserting mechanism.

The awl and the nail block' or throat are moved transversely withrespect to the driver through the actuating lever 39. The awl and nailblock are however returned through independent means. the awl throughthe spring 36 and the nail block through the yielding and positivelyactuated plunger 24. The nail block is positioned in alinement with thedriver by means of the stop 25 on the machine head or frame, and the awlcarrier is arrested by the engagement of the screw or stop 40 thereonwith the stop 40a on the machine head or frame. The adjustment of thescrew 40 enables the feed of the awl to be adjusted. The nail block andawl carrier are therefore arrested by independent stops. The screw 59 isadapted to accurately aline the awl with the driver as is herir-'srt itjustine-nt of the screw 40 for the purpose of varying the .fi-cil willnot disturb the alinemcnt ot the nail bloei; with the driver, and thcadiustment of the screw 59 for the purpose of aiming' the a wl with thedriver will not disturb the feed of the awl nor the position of the nailblock. The positioning means for thc nail block and the adjustments forthe a\vl are therefore absolutely independent so that the adjustment ofone will not disturb the other.

it, is obvious. tuat various changes may be made in tht details ofconstruction Without departing from this invention, and it is thereforeto be umlcrstotal that this invention is, not to be limited to thespecific coni the .-aitl being movable into and out of operativeposition.
